I think you have the tv on digital mode. You need to use you remote to exit out of that mode by pressing the D/A button.

Why am I being told that my signal to my tv is weak and that must come to you for assistance.


Are you on cable or Arial If on Arial you may have to turn the head one way or the other to get the program to come in also weather conditions have a lot to do with this.Weather effects the cable reception as well. If the TV works most of the time but not other times it could be the weather. or a weak booster on your areal

Tv comes on cannot get a picture nor sound. followed instructions in manual regarding source , enter , picture, enter , channel, enter.etc., I can get to the menus but nothing else. It is not on cable...


If you have an antenna, you are trying to receive off-the-air broadcasting. Remember that a couple of years ago the US switched to digital broadcasting and analog stations went off the air. Your TV does not have a digital tuner, so you need an digital-to-analog adapter if you want to receive anything.

The US government had a program before the switch to help pay for the adapters, but that's long past now. Radio Shack sells them as do other retailers, and you can find them online as well.

The adapter picks up the digital broadcasts and converts them to a channel 3 or 4 TV signal that the analog tuner in your TV can receive. Some models of converter also feature video and audio jacks so you can connect it as an AV source like a DVD player. Once you've hooked the antenna to the converter and the converter to the TV, you'll be able to watch your local channels again. Maybe, that is.

The trouble with digital broadcasting is that signal strength makes a huge difference in reception. With analog, a weak signal would still give you a fuzzy but watchable picture. A weak digital signal may not even be detected, or you might get a picture that breaks up (pixelation) or freezes on the screen. You don't say what kind of antenna you have, but unless you're in or very close to a large city or near the station's transmitter, simple rabbit-ears may not be enough. Many people found after getting an adapter that they needed a better antenna, even something on the roof. In some areas (valleys, remote areas, places surrounded by many tall buildings, for instance) people found they could never get any channels. If you do in fact have a digital converter already (you didn't mention one), this could be the reason you can't get anything.

Hope this helps you figure out what's wrong. Thanks for using Fixya!

Digital TV problems


You are suffering from a poor signal. Digital TVs will display 'blocking' (partial freezing of the picture in square or rectangular blocks) or total freezing of the picture, when the signal is too weak.

You don't say if this is a recent problem on a set that has been working correctly - that info. would be helpful. However, things to check include:

Has the aerial moved (wind?)
Are you using a new extension coax cable? If so try another one, as connections may be faulty.
If this a new TV, and you have not used digital previously, your aerial may not be high enough gain for a digital signal, but that is unlikely unless it's a nery old aerial.

I hit a key on the remote and now the TV says, "No Program or Weak Signal." How do I go back to the picture?


If you are using the original TV remote it sounds as if you have pressed the input button on accident... try pressing the input button one at a time until your picture returns....

Good Luck....

Our tv looses it sound as the picture breaks up...many a time it say weak signal


check your signal source, make sure all connections are good. Check that the signal is good at that location with another TV if possible. Check your cable connections, or antana, if using a digital converter box, check those connection as well. if running rabbit years, try to get it as high off the ground as possible. I you have cable or satalite, call your provider for assistance as it is a weak signal.

The picture seems very coarse and has diamonds running across it


Hello: In standard defintion the picture is showing in 480p which is the lowest resolution for LCD televisions, The picture will only look as good as the signal its getting, If you have cable then it should look some what better even with std defintion. The Diamonds/triangles are caused from a weak digital signal or weak broadcast station. This is a normal occurance for LCD televisions as the picture is put on the screen in blocks. I would not say your television is bad, just a poor or weak signal, If you are using a digital antenna and not cable, then you might try purchasing a signal amplifier to boost the signal before going into the set.

The screen shows ''Weak Signal'' and no picture, even though audio is coming through from both the Cable DVR box and Blue-Ray player. The cable box connects to the TV with an HMI cable - all five TV inputs...


Mine did the same thing once. I think all I did was hit the setup on the remote, and let it run back through all the channels and then it worked just fine.

I hope this works for you.

No signal or weak signal


Sorry I see the model,
hold the Menu button on the TV (not on the remote) down for three seconds.
Note: Shop Mode is activated in the same manner: Pressing and holding the Menu button on your TV for three seconds. To avoid accidentally setting your TV to Shop Mode, avoid pressing and holding the Menu button on the TV for three seconds or more.

Weak or no signal message


  1. Since my problem (Samsung/Comcast) began with a channel selection button pushed on the TV remote when it should have been pushed on the cable remote, I figured the problem lay with the TV.  Although I was getting the "weak or no signal" msg., the actual signal strength bar graphic showed it to be strong. Disconnecting did no good. I surmised that the TV was simply not recognizing the box.
  2. I looked at the manual for my Samsung 750 model. 
  3. Page 20 discussed "Selecting the source". I accessed the TV menu and selected "Input", then chose the "HD..." item from the highlighted list. Voila! My tv works again.
